Viridian Vitamin D3 2000iu

Viridian Vitamin D3 2000iu is a high-potency vitamin D supplement providing 2000iu (50 micrograms) of vitamin D3 (cholecalciferol) per capsule, sourced from lichen to ensure vegan suitability. This higher-dose formulation is designed for individuals who require elevated supplementation to correct deficiency, maintain optimal rather than merely adequate vitamin D levels, or who have been advised by their healthcare professional to take a higher dose.

Blood 25(OH)D is the primary marker of vitamin D status and reflects both sun exposure and dietary intake. While the official nutrient reference value for vitamin D is 10ug/day (400iu) for the general population in the UK, health organisations and researchers increasingly recognise that optimal, rather than merely deficiency-preventing, levels of vitamin D in the blood may require substantially higher intakes, particularly for individuals with darker skin, those who are overweight, older adults (whose skin is less efficient at vitamin D synthesis), and those who avoid sun exposure.

Vitamin D contributes to the normal function of the immune system — particularly important given growing research on vitamin D's role in both innate and adaptive immune responses and its association with respiratory health. It also contributes to normal muscle function, maintenance of normal bones and teeth, normal absorption and utilisation of calcium and phosphorus, normal cell division, and maintenance of normal blood calcium levels. Research continues to explore vitamin D's broader roles in cardiovascular health, mood regulation, cognitive function, and metabolic health.

The lichen-derived D3 provides identical efficacy to animal-derived D3. Contains 100% active ingredients, no artificial fillers, and is suitable for vegans. Produced in the UK to Viridian's strict ethical standards.
